Dynamic risk engine

ABSTRACT

Various embodiments of the present invention generally relate to identity authentication and/or recognition. Some embodiments provide a method for determining when a user may engage in a restricted activity, including engaging in an initial contact with a user via a medium for exchange, receiving a request to engage in an activity, determining an activity trust threshold required for the activity, determining an initial identity trust score for the user, and comparing the initial identity trust score with the activity trust threshold. Based on the comparison, the user is either allowed to engage in the activity, rejected from engaging in the activity, or additional identifying information is collected.

CROSS REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. Patent Application No. 13/425,227 entitled “Dynamic Risk Engine,” filed Mar. 20, 2012, which is hereby incorporated by reference in its entirety for all purposes.

TECHNICAL FIELD

Various embodiments of the present invention generally relate to identity authentication. More specifically, various embodiments of the present invention relate to a dynamic risk engine for determining when and whether sufficient identifying information is available to permit a user to engage in a restricted activity.

BACKGROUND

Organizations strive to ensure secure and convenient user access to services or accounts. With the proliferation of identity theft and the growing emphasis on convenience, organizations are forced to find a balance between gathering enough identifying information and making the services or accounts accessible to users. Regulations and business rules may govern how much or what identifying information the user must provide depending upon the nature of the activity that is requested.

Existing systems often sacrifice security for convenience. For example, users may be required to provide a login, password, and answer a secret question simply to view current interest rates. Thus, although the user may be engaging in a low-risk activity, the user may be required to provide an excessive amount of information. Additionally, the risk level of an activity may vary with the user, depending on past behaviors or account preferences.

Further complicating the balance between security and convenience is that organizations have various channels in which users may interact with the organization. For example, users may perform activities related to an account at the organization over the phone, through an internet portal, by mobile phone application, or by face to face contact at a brick and mortar building. Thus, with the different means of interaction and access, organizations must provide various methods of verifying the user's identity.

This creates a need for a flexible way to verify user identity that provides a sufficient level of both security and convenience. Therefore, this disclosure describes a dynamic risk engine for determining when there is sufficient identifying information for a user to engage in a restricted activity and to facilitate equitable comparisons of trust across multiple users, computing devices, and/or channels.

SUMMARY

Methods and systems for determining when a user may engage in a restricted activity are provided. Some embodiments include engaging in an initial contact with a user via a channel, acquiring identifying information relating to the user, receiving, from the user, a request to engage in an activity, determining an activity trust threshold required for the activity, determining an initial identity trust score for the user based on the identifying information, comparing the initial identity trust score with the activity trust threshold. Based on the comparison, the user is either allowed to engage in the activity, rejected from engaging in the activity, or additional identifying information is collected.

In some embodiment, the identifying information includes at least one of information known to the user, a physical attribute of the user, or information identifying a device, wherein the device is associated with the user. In some embodiments, the identifying information includes one or more of: username, password, biometric data, device identification, automatic number identification, token, one time password, or grid card code. In some embodiments, identifying information includes historical user behavior. Historical user behavior may include information related to logon attempts and information related to prior activities performed by the user. Acquiring the identifying information relating to the user may include acquiring information based at least in part on the channel. In some embodiments, acquiring identifying information includes identifying, from a database, security preferences associated with the user. In some embodiments, the channel is an internet portal, face to face contact, mobile application, instant message system, or voice communication. Information in connection with the channel may include location information, device identification, past channel usage, language, network, or internet service provider.

In some embodiments, determining the activity trust threshold required for the activity comprises generating the activity trust threshold based on rules relating to a risk of the activity and information collected in connection with the channel. The risk of the activity may be determined by the type of activity, perceived threats, regulations, transaction amounts, and/or destination of funds. The risk of the activity may be affected by information provided by a third party.

In some embodiments the activity is performed during a session, a session being a continuous dialogue with the user. In some embodiments, the activity is initially performed via first channel during a session with the user, and later, the session is continued via a second channel, where the first and second channels are different channels.

In some embodiments, the user is allowed to engage in the activity only if the identity trust score meets or exceeds the activity trust threshold. In some embodiments, additional information is collected until a revised identity trust score meets or exceeds the activity trust threshold only if the identity trust score is below the activity trust threshold. In some embodiments, a user might be contacted on a new channel in order to raise the user's identity trust score. In some embodiments, a user is rejected from engaging in the activity only if the additional identifying information cannot raise the identity trust score above the activity trust threshold. In some embodiments, rejecting the request to engage in the activity comprises associated a fraud alert with the user.

While multiple embodiments are disclosed, still other embodiments of the present invention will become apparent to those skilled in the art from the following detailed description, which shows and describes illustrative embodiments of the invention. As will be realized, the invention is capable of modifications in various aspects, all without departing from the scope of the present invention. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not restrictive.

DETAILED DESCRIPTION

Various embodiments of the present invention generally relate to identity authentication. More specifically, various embodiments of the present invention relate to a dynamic risk engine for determining when and whether sufficient identifying information is available to permit a user to engage in a restricted activity in addition to an authentication engine that is able to initiate channel-appropriate authentication challenges, in order to increase the identity trust score of a particular session. Existing and future authentication methods or mechanisms may be added, enabled, disabled, or removed from the authentication engine in a manner that does not disrupt or affect the integrity of the dynamic risk engine (i.e., authentication mechanisms are “hot-pluggable.”). Organizations allow users to access services and engage in activities through various channels. Services may include automobile insurance, banking services, health insurance for example, and thus activities may include purchasing insurance, viewing premiums, making account transfers, paying bills, and investing money, for example. The various channels may include face to face contact (video telephones, Skype™, etc.), internet portals, mobile applications, voice communication, instant messaging systems, for example, and each channel may accept unique verifying information. Thus, users may access such accounts and perform various activities relating to the services via the channels when sufficient verifying information has been acquired. For each activity the user requests to engage in, the user is re-authenticated using the dynamic risk engine.

In order to engage in the activity, the user must provide a level of identifying information. The level of identifying information required is determined by an “activity trust threshold.” Various rules and factors such as industry standards and fraud information on a particular activity are used in determining the activity trust threshold. The user's identity must be verified according to the activity trust threshold to engage in the activity.

An “identity trust score” is established for the user. During each user contact, identity characteristics and attributes about the user and his/her device will be collected. The characteristics and attributes collected during contact with a user are stored for future comparison and data modeling. Characteristics or attributes of the user will be assigned a score or level whether individually or grouped characteristics or attributes. When a user attempts to conduct an activity, the identity characteristics or attributes associated with the communication are compared to the known characteristics or attributes stored about the user. All the matched characteristics or attributes scores or levels are summed to total the identity trust score. Incorrect responses, uncharacteristic behavior, or intelligence about specific attributes that apply to a user will either increase the “activity trust threshold” or decrease the user's “identity trust score”. The identity trust score is a measure of the identifying information that is acquired. The identity trust score may be determined by various rules. Identifying information may be information known to the user (e.g., password), a physical attribute of the user (e.g., biometric data), or information identifying a device, wherein the device is associated with the user (e.g., device fingerprint, phone number). Examples of identifying information may include a machine identification, username, password, social security number, token, personal identification number, grid card code, biometric data, or historic user behavior for example.

Various channels allow for various types of identifying information to be acquired. The measure may be numbers or levels, but in either case, the measure corresponds to the activity trust threshold such that the activity trust threshold and the identity trust score can be compared in a meaningful way. In various embodiments, the identity trust score must meet or exceed the activity trust threshold in order for the user to proceed with the activity. If the initial identifying information does not provide an identity trust score that meets or exceeds the activity trust threshold, the user may provide—or the system may acquire—additional identifying information to raise the identity trust score to meet or exceed the activity trust threshold. There may be an initial learning period on each channel such that initially, a user may have to use predefined authentication methods.

For example, a user is requesting to view an account (the activity) via an internet portal (the channel). The risk of the activity and the information collected in connection with the channel are used to determine an activity trust threshold equal to 50 for example. The machine used in connection with the channel is identified as registered, providing an identity trust score equal to 30. Thus, additional identifying information is necessary for the user to view the account. Identifying information such as a correct username and password may provide an identity trust score of 65, and, thus, if provided, the user will be permitted to view the account. If the user cannot provide this information, the user may provide other identifying information and still view the account if the other identifying information satisfies the activity trust threshold. In some examples, the user's behavior impacts the identity trust score. For example, if the user exhibits the same behaviors as the user has done in the past, the identity trust score may be recalculated to reflect this identifying information. In another example, a user wishing to engage in the activity of transferring money from one bank account to another bank account via a mobile application may satisfy the activity trust threshold simply by typing a personal identification number into the application on a certain device. For each activity requested, the user is re-authenticated using the process.

Thus the disclosure describes a dynamic risk engine that determines whether a user will be allowed to engage in an activity based on an activity trust threshold determined for that user and that activity, and comparing the activity trust threshold to an identity trust score calculated for the user. The identity trust score may be dynamically generated as identifying information becomes available. The identity trust score may increase or decrease depending on the identifying information.

In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the present invention. It will be apparent, however, to one skilled in the art that embodiments of the present invention may be practiced without some of these specific details.

Having described embodiments of the invention generally, attention is now directed to FIG. 1, which illustrates an example of an operating environment 100 in which some embodiments of the present invention may be utilized. The embodiments of the present invention illustrated in FIG. 1 allow user interactions with organization 145 through various points of interaction such as, but not limited to, dedicated terminals 110 (e.g., public terminal or kiosk), ATM networks 115 (e.g., interbank ATM network and intrabank ATM networks), mobile devices 120 (e.g., mobile phone), personal computers 125, point of sale (POS) devices 130, face to face contact represented by user 144, or by a landline telephone represented by telephone 142. These points of interaction can include mechanisms for engaging in activities with organization 145. For example, a user may engage in activities such as viewing an account, trading funds, purchasing insurance, submitting or processing a negotiable instrument and may run one or more applications or clients that allow a user to interact with the network. Such applications may provide access to the organization 145 processing systems and interfaces. Thus, the points of interaction allow the user to engage in an activity via a channel. The channels may include face to face contact as shown by user 141, voice communication such as through telephone 142, internet portal or instant messaging such as through personal computer 125, or mobile application such as through mobile device 120.

Dedicated terminals 110 such as public terminals/kiosks may be computers available to the public and/or specially designed kiosks that interact with network 140. ATM networks 115 can be any set of ATMs in an interbank ATM network and/or intrabank ATM network. Mobile devices 120 may be cellular phones, smart phones (a smart phone being a cellular phone that has capabilities and features such as, but not limited to, internet access, a full keyboard, email access, Wi-Fi connection capabilities, BLUETOOTH connectivity, or any other functionality of a computer), tablet computers (a portable computer having a touch interface), netbooks, laptops possibly with a wireless connection (such as an 802.11a/b/g connection or mobile broadband connection, such as via a 3G or 4G wireless network). Personal computers 125 may be any computer (e.g., desktop computers, laptop computers, netbooks, tablet computers, Internet-enabled television devices, etc.) connected to network 140. Dedicated terminals 110, mobile devices 120, and personal computer 125 may be capable of exchanging communication in the form of voice and/or video.

POS devices 130 can be any device used as a checkout or payment receiving mechanism for a merchant or service provider such as a hospital, ambulance company, doctor, automobile repair shop, pharmacy, clothing store, and others. For example, POS device 130 can be a terminal located at a merchant, a computer-based interface such as a webpage or custom application, a telephone payment system, and others.

Network 140 may include a banking network. In accordance with embodiments of the present invention, network 140 can use a variety of interaction methods, protocols, and systems. For example, network 140 can use any of the automated clearing house (ACH) networks. An ACH network may be operated by NACHA (previously referred to as the National Automated Clearing House Association). Another ACH network may be the Electronic Payments Network (EPN). These ACH networks may interact to settle ACH transactions involving a party that has a relationship with only NACHA's ACH network or only the EPN. Other banking networks, such as CIRRUS, NYCE, and PULSE may also be used.

As illustrated in FIG. 1, users may interact with organization 145 via different channels using various points of interaction. Organization 145 may be a membership organization, and the users may be members or potential members of the membership organization. Organization 145 may be a financial institution, or any kind of entity providing any type of service. Organization 145 may be communicably coupled with third party 170. Third party 170 is any organization or source of information external to organization 145 that provides organization 145 with information that may be used in determining an activity trust threshold. For example, information provided by third party 170 may include the identity of IP addresses known to be fraudulent, known mal-ware on systems or networks, etc. Third party 170 may provide information that is specific to a user. For example, a third party may provide information that a credit card belonging to the user has recently been compromised. The information may be stored in security and fraud indicator database 155. Organization 145 may include various computing systems, rules engine 160, user behavior database 150, security and fraud indicator database 155, and user database 165. Rules engine 160 uses information from various databases and third party 170, including information related to the risk of the activity and information acquired in connection with the channel, applies rules relating to the risk of the activity and the information in connection with the channel to determine an activity trust threshold, acquires and uses identifying information to establish an identity trust score for the user, and determines whether the user is permitted to engage in a particular activity. Additionally, the rules engine dynamically generates the identity trust score as information becomes available. The identity trust score may be upgraded or degraded depending upon the identifying information.

Rules engine 160 can be communicably coupled to one or more databases such as user behavior database 150, security and fraud indicator database 155, and user database 165, and may receive information from third party 170. These databases and external sources include information that can be utilized by rules engine 160. For example, user behavior database 150 includes transaction information relating to past transactions the user has engaged in such as the time of day transactions were made, the amount and destination of the transfer, the channel and/or point of interaction used, activities and times associated with those activities (time spent making the transaction), etc. User behavior database 150 may also include information relating to the user's account, such as how many logon attempts have been made, the number of failed logon attempts, the number of successful logon attempts, where the attempts originated from, when and where and from what machine the user has changed passwords, registered devices, and so on. User behavior database 150 may also include information relating to the user's common purchasing habits. User database 165 stores information about users, including employment information, account balances, credit ratings, home ownership information, annual salary, length of membership, and/or other information. User database 165 may store security preferences or instructions that the user has expressed, such as if a requested transaction is over $100 to ask the requestor for a one time password sent to an email address. Security and fraud indicator database 155 stores information relating to information security events, physical security events, cyber intelligence, IP addresses that organization 145 has previously received attacks from, addresses of known fraudsters, known mal-ware on systems or networks, risk scores associated with IP addresses or networks, etc. This information may also be provided or supplemented by third party 170. These events may be related to a particular user, or the events may relate to all users. Thus, this information may impact the activity trust threshold required for an activity globally, or the information may relate to one particular user. In some embodiments, these databases may be integrated into one database. A computer system associated with the organization or authorized third parties may be able to access these databases for account information, user information, security information, and other stored information. In addition, third parties may provide information relating to the user such as the location of the user, a credit score of the user, or any other security information. The rules engine may include many sub-engines that combine scores ultimately.

FIG. 2 is a block diagram illustrating exemplary components that can be included in an identity authentication system in accordance with various embodiments of the present invention. According to the embodiments shown in FIG. 2, the authentication system 200 can include memory 210, one or more processors 220, channel information collection module 230, behavior trending module 250, activity trust threshold module 240, comparison module 260, identifying information module 270, identity trust score module 280, and channel porting module 290. Other embodiments of the present invention may include some, all, or none of these modules and components along with other modules, applications, and/or components. Still yet, some embodiments may incorporate two or more of these modules into a single module and/or associate a portion of the functionality of one or more of these modules with a different module.

For example, in one embodiment, the functionality associated with channel information collection module 230 and identifying information module 270 can be incorporated into a single information collection and analysis module. As another example, in one embodiment, the identity trust score module 280 can be separated into a channel rules module for determining the channel-appropriate authentication rules, a security preferences module for determining the security preferences of the user, and an identity trust score updating module to continuously update the identity trust score as identifying information becomes available. Moreover, the output of these modules can be a channel-specific identity trust score that is updated constantly to authenticate the user according to security preferences.

Memory 210 can be any device, mechanism, or populated data structure used for storing information. In accordance with some embodiments of the present invention, memory 210 can encompass any type of, but is not limited to, volatile memory, nonvolatile memory and dynamic memory. For example, memory 210 can be random access memory, memory storage devices, optical memory devices, media magnetic media, floppy disks, magnetic tapes, hard drives, SIMMs, SDRAM, DIMMs, RDRAM, DDR RAM, SODIMMS, erasable programmable read-only memories (EPROMs), electrically erasable programmable read-only memories (EEPROMs), compact disks, DVDs, and/or the like. In accordance with some embodiments, memory 210 may include one or more disk drives, flash drives, one or more databases, one or more tables, one or more files, local cache memories, processor cache memories, relational databases, flat databases, and/or the like. In addition, those of ordinary skill in the art will appreciate many additional devices and techniques for storing information which can be used as memory 210.

Memory 210 may be used to store instructions for running one or more applications or modules on processor(s) 220. For example, memory 210 could be used in one or more embodiments to house all or some of the instructions needed to execute the functionality of channel information collection module 230, behavior trending module 250, activity trust threshold module 240, comparison module 260, identifying information module 270, identity trust score module 280, and channel porting module 290.

Channel information collection module 230 is configured to engage in an initial contact with a user via a channel, and in doing so, it is further configured to receive, collect and/or acquire information in connection with the channel, including location information (e.g., region, city, ISO country code, global positioning system information), machine or device identification, internet protocol address, the type of network (e.g., cable, dial-up, digital subscriber line, fiber-optic internet, mobile), language, and internet service provider. For example, the information collection module 230 may detect that the user is using a particular device that is registered with the organization. Some information acquired by the channel information collection module may be used in determining an activity trust threshold. For example, if a user is determined to be located in France, more identifying information may be required from the user as compared to a user determined to be located in the United States, even if the users are requesting to engage in the same activity.

Behavior trending module 250 compiles, mines, and/or models data related to historic user behavior. The historic user information is compared to the user's activity to provide additional identifying information. The identifying information may be used in determining an identity trust score for the user, and may be collected continuously during the session. For example, behavior trending module 250 may compile information related to logon attempts for the user including the number of successful and unsuccessful logon attempts, the number of connection events, the time period the attempts were made in, historical user channel information, the type of activities the user has requested, the time of day the user requests the activity or similar activities, the nature of the activities, etc. This identifying information is used in determining an identity trust score for the user requesting to participate in the activity. The user's identity trust score may dynamically change during a session depending on the user's activities as analyzed by the behavior trending module 250. For example, a user's identity trust score may initially be high enough to view an account balance, check charges on a debit card. However, to transfer money from one account to another account may require additional authentication to increase the user's identity trust score. The user's identity trust score may increase if the user follows the same behavior on the website as the user typically does. For example, assume the user typically logs in and spends five to ten seconds on the summary page, followed by checking credit card charges for a few minutes, and then reviews several stock prices. If the user does some or all of the actions prior to or while requesting the transfer, the identity trust score would have increased since the user's initial logon. Thus, a user requesting to engage in a generally high risk activity may engage in the activity if the user has a history of engaging in the activity in a manner consistent with past behavior. This use of past user behavior may also decrease the identity trust score. For example, if the user's browsing behavior is incongruent with past browsing behavior, then the user's identity trust score may be lowered. Thus, the behavior trending module may be used in determining the user's identity trust score based on any number of factors including the number of logon attempts and historic user behavior.

Activity trust threshold module 240 is configured to determine an activity trust threshold for the activity. The activity trust threshold sets a minimum identity trust score required for a user to engage in the activity. Activity trust threshold module 240 accesses information collected and/or processed by channel information collection module 230 and behavior trending module 250, and other general information relating to the risk of the activity. In some embodiments, the activity trust threshold module 240 may use information provided by third parties including information that is specific to the user and/or information that may be applied globally. The information is used in determining the activity trust threshold. In some embodiments, determining the activity trust threshold includes generating the activity trust threshold based on rules relating to a risk of the activity and information collected in connection with the channel. A risk of the activity may be determined by the type of the activity, perceived system threats, regulations, transaction amount, time of the activity, destination of funds, and/or any other factors. Other factors or information in connection with the channel may include channel risk, ground speed (miles per hour to travel between the logon location and the previous logon location), the number of days since the last address change, number of alerts on the user, etc.

In some embodiments, the activity trust threshold module may include a scoring system in which the value of each factor is given a score. In some embodiments each factor is weighted according to its significance. The scores may be combined in any desired manner to determine an activity trust threshold. Any number of factors may be used to determine an activity trust threshold for any user, engaging in any activity via any channel, providing a flexible system. Additionally, in some embodiments, various factors described as used to determine the activity trust threshold may be used instead in determining the identity trust score, and vice versa.

Identifying information module 270 is configured to acquire identifying information associated with the user. Identifying information collected by the identifying information module 270, in combination with information supplied by the behavior trending module 250 is used in the identity trust score module 280 to determine an identity trust score. Examples of identifying information include a password, username, biometric data, device identification, phone number, token, one-time password or grid card. In some embodiments, identifying information module 270 collects identifying information according to channel. For example, identifying information if the channel is an internet portal may include device identification, username and password personal identification number, and a token, whereas identifying information if the channel is a voice communication may include ANI, voice biometrics, and a token. A set of channel rules may determine the order that the information is collected, if at all. Some identifying information is collected automatically and continuously. For example, if the channel is voice communications, the identifying information module 270 may analyze the voice as the user speaks, thus providing identifying information to the identity trust score module 280. In some embodiments, the identifying information module 270 requests the user to provide additional identifying information. The request may be made if the identifying information is not satisfactory for the user to engage in the activity because the activity trust threshold requires more identifying information. Or the request for additional identification may be made consistent with security preferences expressed by the user. For example, the user may have requested that any transaction over a certain amount requires the user to enter a PIN. Or the user may have indicated a rule disallowing wire transfers or transfers to certain countries.

The identity trust score module 280 is configured to determine an identity trust score for the user based on information acquired by the identifying information module 270 and the behavior trending module 250. In some embodiments, the identity trust score module 280 performs channel-appropriate authentication by determining an identity trust score for the user based on the identifying information acquired from the identifying information module 270. Thus, the identity trust score may be a number or a level of information that corresponds with the activity trust threshold. If the activity trust threshold level is low (indicating that the risk is low or trust is high), less identifying information is necessary for the user to engage in the activity. In some embodiments, each channel is governed by channel-specific rules. For example, on a voice telephone call, determining only the phone number may result in an insufficient or low identity trust score. However, if the user's voice is authenticated, the user will then automatically be authenticated to a much higher level, resulting in a higher identity trust score. In another example, a user attempting to fill out a loan application online scores a certain identity trust score simply by using a machine that is recognized. However, the user will score a much higher identity trust score if the user provides a username/password combination. Thus, some factors collected in connection with the channel as well as historical user behavior are integrated together by some weighted formula to dynamically generate an identity trust score.

Once the identity trust score is determined by the identity trust score module 280, the comparison module 260 compares the identity trust score with the activity trust threshold. If the comparison module determines that the identity trust score meets or exceeds the activity trust threshold, then the user will be permitted to engage in the activity. If the comparison module 260 determines that the identity trust score is lower than the activity trust threshold, then the user is either rejected from engaging in the activity or the user may be asked to provide additional identifying information to raise the identity trust score. If additional identifying information becomes available (e.g., the identifying information module requests more information or collects it automatically), the identity trust score is re-calculated with the new information and the revised identity trust score is compared with the activity trust threshold. In some embodiments the identity trust score is dynamically generated, sometimes by information provided from the behavior trending module, and, thus, the identity trust score is being constantly updated without additional requests from the user. In some embodiments, the user has exhausted all methods of authentication in that channel but has been unsuccessful in raising the identity trust score to the necessary activity trust threshold level. Thus, the user will be rejected from engaging in the activity. In some examples, the activity trust threshold is determined to be too high and the user will be rejected without being asked for additional identifying information. For example, if the information collection module determines that the user is accessing an account from certain countries or regions, the request may simply be rejected because the activity trust threshold determined by the activity trust threshold module is simply unattainable.

The following is an example of how the dynamic risk engine may be used. A user wishes to engage in wiring money from an account in the United States to an account in China. The channel is an internet portal. Before the user has logged in or requested to engage in the wire transfer, the channel information collection module has collected some information such as location, internet service providers, network, and provided the information to the activity trust threshold module. The information collection module has determined that the user is located in China and that the internet service provider is AOL. Each of the values of these factors is given a predetermined score perhaps determined by industry standards. For example, a location of China may be given a certain score indicating that the trust level for this user is not high. The internet service provider may be one that is trusted, indicating a high level of trust. However, the location information may be more significant in determining the activity trust threshold and may therefore have a greater impact on the overall activity trust threshold. Thus, some factors in connection with the channel as well as the factors related to a risk of the activity are then integrated together by some weighted formula to determine an activity trust threshold for this user to engage in this activity. Thus, as illustrated in the example, the activity trust threshold is determined by various rules related to the risk of the activity and information in connection with the channel. Next, an identity trust score is determined. As mentioned, information in connection with the channel including the device identification has been collected. Next an initial identity trust score is determined. It is determined that the device is has been registered in the system or that the user has used in the past. Additionally, the user provided a correct username and password. An initial identity trust score is determined based on this identifying information. The behavior trending module supplies information that the logon attempt was successful on the first attempt, that the user is currently deployed to China, and that every Saturday, at a similar time, the user wires money from an account in the United States to an account in China, consistent with the user's actions today. Additionally, when the user logged in, the user checked a credit card balance prior to request the transfer, as the user typically does. Thus, the identity trust score is raised because the user is acting in accordance with historical user behavior. As described, the identity trust score is then compared to the activity trust threshold to determine whether additional identifying information is necessary. If so, the identity trust score is regenerated as the information becomes available.

In some embodiments, authentication system 200 includes a channel porting module 290 configured to transfer a user on one channel to a second channel that is different from the first channel, during a session. The channel porting module 290 allows the session to seamlessly be transferred to a different channel. Thus, an identity trust score and activity trust threshold in connection with the second channel may be determined and compared. If enough identifying information is available (the identity trust score meets or exceeds the activity trust threshold), the session will be continued on the second channel. Thus, the information collected in connection with the first channel may be used to authenticate the user on a second channel. In some embodiments, the user may not be required to provide any additional identifying information for the session to be continued on the second channel.

FIG. 3 is a flow chart illustrating a set of exemplary operations for determining whether to allow a user to engage in a restricted activity in accordance with some embodiments of the present invention. In block 310, a user engages in a contact via a channel. Also in this block, identifying information relating to the user is acquired. The channel may be a mobile application, an internet portal, voice communication, instant messaging system, or an in-person visit to a brick and mortar building. Thus, a number of devices or no device may be used in making the contact. The user may or may not have an account with the organization. In an example, a contact may include a visit to a website, and identifying information may include device identification.

In block 320, a request is received for the user to engage in an activity. The activity may be to view a particular webpage of the organization, transfer funds, fill out a mortgage application, browse interest rates, compare insurance rates, purchase insurance, deposit a check, for example.

In block 330, an activity trust threshold is determined for the requested activity. In some embodiments, determining the activity trust threshold includes generating the activity trust threshold based on rules relating to a risk of the activity and information collected in connection with the channel. Some or all of the information may be assigned scores and totaled to generate an activity trust threshold. In some embodiments the information is weighted depending on the significance of the information. As described above, the activity trust threshold sets a minimum identity trust score (level of identifying information) that must be acquired for the user to engage in the activity.

In block 340, an identity trust score is determined for the user. The identity trust score is determined based on the identifying information acquired. In some embodiments, the identifying information is based at least in part on information in connection with the channel. In some embodiments, the identifying information is channel-specific. Identifying information may include information such as a username, a password, biometric data, a device identification, an automatic number identification, a token, a one time password or a grid card code, for example. Identifying information may also include information collected or compiled in connection with the user's historic behavior. For example, if the user acts in accordance with typical behaviors, the user's identity trust score may be increased. Or, if the user acts inconsistently with past behaviors, the user's identity trust score may be decreased from the initial score.

In block 350, the identity trust score is compared with the activity trust threshold. Next in block 360, based on the comparison, the user is allowed to engage in the activity, the user's request to engage in the activity is rejected, or additional identifying information is requested from the user or collected automatically.

FIG. 4 is a flow chart illustrating a set of exemplary operations for determining whether to allow a user to engage in a restricted activity in accordance with some embodiments of the present invention. Blocks 410-450 represent the same steps as discussed in blocks 310-350. At block 460, a determination is made whether the identity trust score meets or exceeds the activity trust threshold. If the identity trust score meets or exceeds the activity trust threshold, in block 470, the user is permitted to engage in the activity. In block 475, information related to the activity (e.g., type and nature of activity, channel), results, and behavior (e.g., number of attempted logons, time of day) is recorded for future use. Alternatively, if the identity trust score does not meet or exceed the activity trust threshold, block 480 determines whether the identifying information acquired in connection with the channel is exhausted, and whether other identifying information such as past user behavior data is available. If all identifying information has been exhausted, then in block 490, the user is rejected from engaging in the activity. In block 495, information related to the activity, results, and behavior is recorded. In some examples, the information may include associating a fraud alert with the user. If additional identifying information may be acquired, then in block 492, additional identifying information is collected or acquired. The collecting operation may be performed automatically or the user may be requested to provide additional identifying information. For example, while on the phone, the user's voice may be authenticated and thus the identity trust score is revised. Or the user may be asked to provide a one time password. Or the user may have acted in accordance with previous behaviors, thus raising the identity trust score. After the additional information is collected, the operation returns to block 440 to determine a revised identity trust score for the user, and to block 450 for the comparison operation. The process continues until the user is rejected or allowed to engage in the activity.

In some embodiments, situations exist in which no amount of additional identifying information will permit the user to engage in the activity. For example, if the user's location is determined to be in a country that raises the activity trust threshold to an extremely high level (e.g., requiring biometric data such as hair samples to reach an acceptable identity trust score), no amount of identifying information in that channel may overcome the activity trust threshold and thus the user is not permitted to engage in the activity. In another example, security preferences provided by the user may restrict activity. The security preferences may include rules pertaining to what activity is allowed or rules that restrict when activities can take place.

FIG. 5 is a flow chart illustrating a set of exemplary operations for a porting feature in accordance with some embodiments of the present invention. In block 510, a user is engaged in an activity via a first channel. In block 520, the user requests that the session be ported to a second channel that is different than the first channel. In block 530, the user is authenticated on the second channel. In block 540, the user's session is ported to the second channel and the user can continue to engage in the activity. For example, the user is attempting to fill out a mortgage application using a mobile phone via a mobile phone application. The user may choose to complete the application during the same session but chooses to continue filling out the application on a personal computer. The activity trust threshold for this activity is determined to be low, and the user is authenticated simply by the device identification. Thus, the user can complete the application during the same session.
